[Q] [HELP] Problem is MT driver

Hello, I have problem with driver MediaTek DA USB VCOM. I have succesfuly instelled it. But when I plug my phone ZTE V970 in device manager it will show up for like half a sec then dissapear. So I cant flasg the phone since the SP flash tool cant see the path.
I also tried intall it via SD card. But when it goes to recovery (all in chinese) And I try to intall it by choosing the right ROM it will give the the answer that ROM file cannot be opened. The ROM is from XDA and in .7z format and I also found the .zip format. both didnt work.
I think if i can manage to tell my PC to see the driver then I can easily flash it. I am stuck on this step for few days already.
Also tried 2 another PCs and still didnt work.
I am runnig win7 64bit system.
Can someone please tell me where is the problem?
Thank you very much.

got the driver details
I managed in that half sec to click on the driver and look at the details. It gave me this:
Currently, this hardware device is not connected to the computer. (Code 45)
To fix this problem, reconnect this hardware device to the computer.
The driver name is: MediaTek PreLoader USB VCOM port (COM3)
Even after updating it and choosing the right driver (also from this forum).
When I turn phone up I will get that theres new device Android MT65xx and code 10.

I have exactly the same problem
I have exactly the same problem, how did you solve it eventually?

What is the error on flash tool log file ?

Problem is MT driver
IFor Windows 8, I installed MT driver force install of un-signed drivers , now its not showing yellow icon in device management but it comes for few seconds and disappears. If I connected phone with battery inserted, MT driver comes and disappears in device management. Due to this problem I am not able to update from 4.1 to 4.2, Can we update from Mobileuncle software, if not please suggest solution for this problem

Problem solved, even though it comes and goes, it doesn't affect flashing. I updated to 4.2.1
Sent from my Micromax A116 using xda app-developers app

[Q] Odin don't see my tablet in download mode

When I plug in my p3113 into the computer while in download mode, it tries to install driver software, it does, then tells me the device was not successfully installed, I have Samsung USB drivers installed from kies, I've tried different usb ports to no avail.
I've been rooting phones since the G1, I've been through this process several times with several Samsung devices and have never had this problem, so is my computer just old or what?
I am running a fresh install of W7 Ultimate service pack 1. Don't come at me with searching either because I have and haven't found a solution.
Would like to get this done so my kids can continue downloading games, don't really wanna have to use someone elses computer but that is what it is gonna have to come down to unless someone here knows the answer to my problem.

Seems you know what you are doing. Only thing I can think of....did you turn USB debugging on? I believe it needs to be on for Odin.

Also do you have the proper drivers? If you install Kies and plug in your phone, your comp will download the needed drivers for your device, perhaps this may help

Galaxy S6 not recognized on PC or ADB

Dear,
My Galaxy S6 SM-G920F with lollipop 5.1.1
AP : G920FXXU2BOG8

The pc doesn't recongnise it on device manager (i have a win 7 pc), the phone however react as pluged in a charger.
their is no mtp or mass storage switch on notification.
i have reinstall the driver of samsung several times with smart switch & also made it manual by suppressing directrly the samsung usb driver from programs on control panel then reinstall it but no hope.
I can't figure out eitheir its hard or soft.
i had change my cable & also test my pc with another Galaxy s6 it works fine, but mine no.
i have made wipe cache / factory reset also made an initialisation from parameters the phone is formated but not recognised by the pc also test it on another pc but the same behaviour windows pcs doesn't recognise my phone.
However, i figure out that when its on the restore mode (volume down + lock + home) the pc recognise it by Odin and smart switch.
i install the same rom on it also made an emergency restore with S/N and model and the process completes fine with smart switch and i saw the donwload progress bar completing on my phone.
but still i m stuck its not recognised please help !!!
i tries to use *#0808# and its on AP / MTP + ADB but no hope
i plug it on ADB android studio but the device list is empty :'(

i used different cables and pcs but still not recognised
yesterday i used odin with those options :
BL/AP/CP/CSC and checked
Auto-reboot
F.reset Time
phone EFS Clear
Phone bootloader update
it has taking some while to execute but after that my phone was working and detectable again by my pc the problem was resolved for a couple of hours, in the evening the problem occured again.
and i have tried the process again the same why but no connection at all.
i don't know if its a hardware problem or software related problem
because the usb work when i m in restore mode (Odin mode) otherwise no.
Its an advance problem i already check all about usb / cable and pcs related problem.

Problem resolved
I sent my S6 to Samsung SAV it take them 4 days.
they doesn't give me proper answers on what they have done but i saw that my mini-usb plug is new so i expect that they got this part changed accrodingly the samsung has no sign of damage its a clean operation.
Its now detectable. It was indeed a Hardware problem

i have the same issue but in a g928f
today i changer my lcd with the micro usb flex
so all is new except the main board and still is not recognised at any pc with any cable.
i am really starting to feel very sorry for this phone.
odin does not see it at all even at download mode.
i don't know what else to do.

Software or Hardware Issue
I have a s6 920t that I am suppose to pay for at the end of the day. I got it from a friend who bought it while overseas. The only time my computer detects it is in download mode/odin mode, I hear the sound and I see it as "Added". When I try to connect any other way I don't hear the sound my laptop makes when it has detected a new device also otg cables don't work. I just simply want to know if this a software or a hardware issue? Software I can fix but if it is hardware I don't want to waste my money. Please anyone reply as soon as you can so I can decide what to do.
Thank you

I have two S6 Edge and one of them started doing this (phone only appears on USB when in Download mode). When swapping the motherboard between the phones, it works. So the problem isn't with the motherboard, but the USB connection module attached with the ribbon cable... There must be a chip on the module which gets locked somehow and replacing the board is at least one way to fix it. Hopefully someone finds another method without replacing the charger board?

HELP! Can't connect to PC

Hi guys, i'm getting this problem and cant connect to pc and i think i've tried it all.
when i connect my phone to the PC, it stars charging but my pc doesn't recognize the device, and my phone doesn't show the notification to make it file transfer.
Could it be a computer issue?
it seems not, i've uninstalled and installed drivers (ADB and Fastboot, oneplus drivers, google drivers) and the problem persist, and even try it on another computer and its the same, the phone does not appear even on Device Manager.
Could it be the Cable?
I don't think so, i'm using the original oneplus cable, it use to work really well before, and i have even connect other phone with the same cable and the other phone is recognize by the computer, so it''s not a cable issue... but I still when to a Tech-store and try other USB-C cables with their computer but my issue still persist (phone isn't recognize, just charge).
Could it be a phone software issue?
Maybe? but i discover this issue 3 weeks ago and a i was on EVOX rom and i thought it would be solved flashing another rom, and i CLEAN FLASH Resurrection Remix Rom, but then the problem was still there!
cant connect even on FASTBOOT MODE...
BTW, before installing RR, i Installed OOS 10.3.4, and still my computer doesnt recognize the phone, YES i have enabled developer options and USB debugging is enabled, and USB PREFERENCES to File transfer, but its not helping me, the "usb for" option its all grayed out and cant change that.
Right now i'm stuck on a RR build without Gapps, and i lost ROOT and RECOVERY, and as you may think, i cant install any of them because i cant connect to my pc, so i'm in a pretty difficult situation here hehe, could you please help me out?

This helped me. Hope it works for you too

Thanks for your reply, but this didn't work because my device isn't shown on device & printers, or anywhere as far as i checked...

PROBLEM SOLVED.
I think this is the silliest solution I've ever seen, it was just DUST, i clean my USB-C PORT (with a mask xD) and then pluggin, AND VOILA, it worked!!! so keep your ports clean everyone
